AEM 12 Position Universal Trim Pot - Universal
AEM builds this trim pot as a simple, reliable way to fine tune your engine management system on the fly. It works with virtually any ECU setup, including the AEM EMS, giving you a physical dial to dial in critical parameters without plugging in a laptop.
This listing covers the Universal 12 Position Trim Pot, SKU 30-2056, suited to any vehicle running a compatible engine management system. It's not tied to a specific make or model, so fitment comes down to your ECU's wiring and inputs rather than the car itself.
